` 1 Claim.

My invention relates to apparatus for clearing snow from highways andthe like and has among its objects and advantages the provision of animproved snow plow.

An object of my invention is to provide a snow plow designed to cut aclear path in combination with means for lifting the snow anddischarging it laterally of the snow plow.

Another object is to provide a snow plow shaped to cut a clear pathwithout disturbing the snow immediately adjacent the path together withnovel means for elevating the snow removed from the path withoutinterference from the side walls of the path.

Another object is to provide a snow plow shaped to remove snow with aminimum of resistance in which the plow is so shaped as to be 1 capableof widening the additional-path. The plow is characterized by twovertical walls spaced to dene the width of the path together with 'acentral divider. The plow is so shaped as to be devoid of side pressurewhen trimming the edge of a path for widening purposes. For wid eningpurposes,one side of the plow only is employed but the snow clearingdesign is such as to outa vertical wall and lift the snow to a positionabove the normal snow line and throwthe elevated snow laterally of thebank.

With these and other objects in view, this in' ventionV consists incertain'novel features of construction, combination and arrangement ofparts to be hereinafter more fully described and claimed. Y

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which:

Figure 1 is a perspective view of my snow plow;

Figure 2 is a side elevational view; Figure 3 is a top plan view; and lFigure 4 is a sectional view alongthe line 4- of Figure 3.

In the embodiment selected to illustratemy invention, I make use of aninclined floor I0 provided with blades I2 at its forward end. Blades I2may be attached to the floor ID byrivets I4.

To the side edges of the iioor lll I connect vertical walls IB. Thewalls I'B are arranged at right angles to the oor I0 and may be weldedthereto. Walls I6 include vertical extensions I8 having leading orcutting edges 20. Extensions I8 are of such height as to extend abovethe normal snow line. y

Midway between the extensions I8 I position a divider 2| which lies onthe floor I0 and terminates in two moldboards 22. Moldboards 22delaterally of the snow plowabove the normal snow line. Extensions I8are interconnected through the medium of a bar 24 which is bent toprovide right-angular reaches 2B welded to the extenj sions I 8. Divider2l includes an extension 28 which is welded to the bar 24as at 30.

In my invention, the snow is forced up a gentle incline toa point abovethe snow line, at whichl time the snow is deflected laterally throughthe medium of the moldboards 22. The snow removing action lof -my plowis devoid of any lateral pressure on the remaining snow banks. The onlysnow being moved is that which is being elevated up the inclined iioorI0, while the extensions I8 cut vertical walls in the remaining snow. Ineliminating side pressure, I provide a plow with a larger removalcapacity capable of being drawn with much less power than is necessaryin plows having a deflecting action' against the walls of the path beingcleared. The extensions I8 are of suicient height to cut evenly throughthe `snow even when several feet deep. The extensions I8 hold the snowon the plow until it is elevated suniciently -far to be dis` y chargedabove the surface of the snow.

The rear edge of the floor I8 between the molded of lighter material andwill handle an ex--l ceedingly large amount of snow with a relativelysmall amount of power. yThe lifting and deflecting action is such as to'be burdened with the snow actually lifted from the cut only. The plow isdevoid ofany side pressure with the walls of v the path being out.

The extensions I8 are spaced from the moldboards 22 to provide outlets32. I curve the extensions I8 at 34 to provide a coniiguration whichfacilitates lateral throw of the" snow. Moldboards 22 are cut away at 36to provide clearance with respect to the vertical snow banks. Thedivider 2l' aswell as the moldboardsl 22 may be welded tothe inclinedfloor I0 thus'lending reenforcement thereto, in addition to effectivelyconnecting the parts.

I claim:

A snow plow comprising a flat, inclined lifting oor having its lower endbladed, side walls carried by the lifting floor for supporting thelatter in said inclined position, said side walls having verticalextensions lying in a common plane therewith and projecting above thelifting floor at its lower'end for cutting a clear path inthe snow, adivider on said'lifting floor comprising a vertical wall positioned onthe lifting floor midway between said extensions and paralleling thelatter, said vertical wall terminating in two moldboards ciuvedoutwardly and rearwardly of the lifting floor for deecting the Snowlaterally of the higher end of the lifting floor, said extensions havingconVeXed rear edges spaced from their respective moldboards to provideoutlets for the snow.
